MASS

Another characteristic of matter is mass. Mass is the amount of matter in an object. Look at the 3 objects below, all are made up of matter and have mass. Which one has the greatest mass?

MEASURING MASS The Triple Beam Balance is the tool we use to measure mass. Unit of measure for mass is grams (g), milligrams (mg) and kilograms (kg) s/triplebeam/ d/review_scimethod.html interior.html

WEIGHT

Weight is a measure of the gravitational force exerted on an object. Gravitational force keeps objects on Earth from floating into space. The more mass an object has the greater the gravitational force on the object and the greater the object’s weight. ce/energy_electricity_forces/forces/revisi on/3/

UNITS FOR MEASURING WEIGHT Weight is expressed in the SI unit of force, Newton (N) One newton = an object that has a mass of 100g on Earth. A spring scale measures Newton's

INERTIA

Inertia is the tendency of an object to resist a change in motion. An object at rest will remain at rest until something causes the object to move. A moving object will keep moving at the same speed and in the same directions unless something acts on the object to change its speed or direction. Mass is a measure of inertia.
